What is methamphetamine addiction?
Methamphetamine impacts the central nervous system and is a potent, highly addictive stimulant. A kind of the drug known as "crystal methamphetamine" has the appearance of shiny, bluish-white pebbles or glass fragments. It shares chemical similarities with amphetamine, a medication used to treat narcolepsy and attention-deficit/hyperactivity disorder (ADHD).
Methamphetamine increases the amount of the natural chemical dopamine in the brain. Dopamine is involved in body movement, motivation, and reinforcement of rewarding behaviors. The drug’s ability to rapidly release high levels of dopamine in reward areas of the brain strongly reinforces drug-taking behavior, making the user want to repeat the experience.
